+Monitor wip
+===========
+
+- Name: wip - wakeup in preemptive
+- Type: per-cpu deterministic automaton
+- Author: Daniel Bristot de Oliveira <bristot@kernel.org>
+
+Description
+-----------
+
+The wakeup in preemptive (wip) monitor is a sample per-cpu monitor
+that verifies if the wakeup events always take place with
+preemption disabled::
+
+                     |
+                     |
+                     v
+                   #==================#
+                   H    preemptive    H <+
+                   #==================#  |
+                     |                   |
+                     | preempt_disable   | preempt_enable
+                     v                   |
+    sched_waking   +------------------+  |
+  +--------------- |                  |  |
+  |                |  non_preemptive  |  |
+  +--------------> |                  | -+
+                   +------------------+
+
+The wakeup event always takes place with preemption disabled because
+of the scheduler synchronization. However, because the preempt_count
+and its trace event are not atomic with regard to interrupts, some
+inconsistencies might happen. For example::
+
+  preempt_disable() {
+	__preempt_count_add(1)
+	------->	smp_apic_timer_interrupt() {
+				preempt_disable()
+					do not trace (preempt count >= 1)
+
+				wake up a thread
+
+				preempt_enable()
+					 do not trace (preempt count >= 1)
+			}
+	<------
+	trace_preempt_disable();
+  }
+
+This problem was reported and discussed here:
+  https://lore.kernel.org/r/cover.1559051152.git.bristot@redhat.com/
